What is probiotics?

Probiotics are live microbes that, in enough numbers, support the gut's own bacteria. Different strains do different things: some are studied for antibiotic-related diarrhoea, others for bloating or regularity. Look for the strain names and CFU count on the label, and take them consistently for at least 4–8 weeks.

Forms. Capsules, sachets, drink powders and fermented drinks. Look for named strains, CFU at expiry, and storage instructions.
